ROTARY PRINTING-PRESS.

Specification of Letters Patent.

Patented Jan, 26, 190,9.

To all whom 'it may concern:

Be it known that I, FREDERICK M. TURCK, a citizen of the United States,and resident of Rosebank, in the county of Richmond and State of NewYork, have invented certain new and useful Improvements in RotaryPrinting-Presses, of which the following is a specilication.

The invention relates to improvements in rotary printing-presses of theclass described in my prior patent No. 830,751, dated September 11th,1906, and to which reference may be had for a full description of thecomplete machine.

rPhe present invention includes a single impression cylinder cci-actingwith a pair of type cylinders upon a web of paper, and the obycct is toprovide meansfor readily varying the diameters of the several cylindersto secure an increased printing range for the machine, whereby severalsizes of printed sheets may be obtained.

A further object provides for the rapid and accurate operativeadjustment of the several cylinders.

rl he invention also p`r ovides means for releasing the pressure uponthe impression cylinder to permit the web of paper to be introduced orthreaded and accurately adjusted in relation to the several partscomprising the machine.

1n describing the invention in detail reference is had to theaccompanying drawings, forming art of this specification, and 'wher-e inlike ciaracters of reference are used to designate like arts throughoutthe several views, and in wliich- Figure 1 is a side elevation of a partof the machine pertaining to the resent invention. Fig. 2 is a groundplano a ortion of the rear frame of the machine, in W lich are journaledone end of the several cylinders with their respective driving gear.Fig. 3 is a transverse sectional view of a part of the front frame,illustrating the journal-boxes carrying the opposite end of thecylinders. Fig. 4 is a detail transverse section of one of thecylinders. Fig. 5 is a spacing block adapted for use in connection withthe lower type cylinder.

umerals 1 and 2 designate respectively a portion of the front and rearframes of the press, each of which frames being provided l ders, asindicated by thedotted circles 3, 4

and 5, the gears for cylinders 4 and 5 being respectively designated by4and 5, These gears interinesh with one another and are in turn drivenby the pinion-gear 6, fixed upon the shaft 7, the frame and providedwith a driving pulley 8.

The im ression cylinder is provided with the usua blanket and connectingmeans therefor, and to the two type cylinders are aflixed the printingforms with their necessary attachments.

When it is desired to increase the dialneters of the printing couples,consisting of the impression cylinder andthe two type cylinders, a twopart jacket 9, (see Fig. 4) preferably formed of metal, is removably secured to the body of each ol` the cylinders and over the ackets, aresecured respectively the aforementioned blanket and printing forms.Driving gears corresponding to the increased diameter of the cylindersreplace the former ones and these operatively engage with one anotherand with the pinion gear 6.

The changes in the diametrical dimensions of the printing couples areaccomplished without the removal of the several cylinders from theirjournal-boxes and without dis` turbin the horizontal path of the printedweb, tie latter object being essential in the further action of thepress and the former purpose insures a considerable saving of time inits operation. For the accornp ishnient of these objects with respect tothe upper type cylinder 4, journal-boxes 10 are provic ed havingeccentric boxes to receive the journals of the cylinder, the boxes beingrotatably mounted inthe frames and secured in operative position withbolts. Upon the removal of the bolts, pin-wrenches may be utilied toengage the bolt perforations in the boxes to turn the latter for proerly ositioning the dual-size cylinder inicate by the broken circles 4and 4b, such position permittin the respectivecylinder-gearsto engage te common pinion-geert and -to colatter being journaled in the ed invertieally-slidiinr boxes 112, which hitter i ai 1guided bv theI'rztnies ol thil prees :nld by tlw` sido blocks I3. 'l`h4l constructionand tuition ol' the eccentric Journal-boxes ll rire similar to that olAboxes l), in that it permits the duel size impression cylinders 13 :indSi" and their connected genre to roepen tively cn-A gitge theirioircsponiling type cylinder; nod gears 4 and fill.

'lhe lower type cylinder 4 is nionntml in the horizontalI yhulii[ablejournal-lirios 111, whieh. nre -gnided and supported by tho l'rauics ol'the press. The ziperal-ive pi il ion. olA this type t 'linder withrespect lo iis co acting inip'reusitm rylinder is innintnincd by theailjustingscrews 15, which urge the journaldioxcs against the heed sidoblocks 13. The adjustment of these boxes in rele tion to side bloc-lis1? l'orrthe :tcroininodntion of the enlarged type cylinder 5b, acting inconnection with the enlarged impression cylinder Z5", is obtained byinterposing spat-ing blocks 1b, shown in detail in Fig.

The frames 1 and 2 nre provided with re I (fesses below the slidinglboxes 12, end within the recesses ore mounted the rerrierdiloeks 1Twhich engage eeeentries 1S, l'ornied on` shaft 10, the latter beingrotatably mounted in the frames ol the press and actuated by the bruidlever 2G to operate the verrierbloclis lor raising and lowering thesliding boxes 12, which support the impression cyl inder.

t will be evident that by means ol the adjusting-screws 15 the operativeContact between type cylinder 5 and impression eylv inder S3 may bereleased, sind through the operation ol the hand cylinder may beseparated from the upper type cylinder L1, whereby the web ol' peper maybe introduced couples and through position properly adjusted.

21 designates an ink-distribetingI cylinder adapted to be rotatedthrough its connected f l driving gear 22 from the pinion neer 6, and isarranged to rece've a supply of ink from :in

ink fountain in t 1e usuel manner, and 23 and 24 indicate conventionalforni rollers for ap.- plyineT the ink to the printingr cylinders.

, As the operation'of the various parts of the machine have been set outin detail end in the connection wherein theyv cooperate with each otherit is believed a reca pitulation ol the en tire operation isunnecessary. It is apparent, of course, while l illustrate end describethe preferred embodimentl of the invention it is susceptible of variouschanges as regards lever 2t) the impression between the printing` thenmoh'uie. and its l its form, proportion, detail construction, endarrangement of parts without departing from the essential spirit andscope or sacri- Iicinir nny of the advantages of' the invention.
